Controller SAS Port
The SAS ports are used to connect the base unit to additional disk enclosures and have two Status LEDs, a
green Link LED on the left and an Orange Fault LED on the right.
iSCSI Host Ports
The ports labeled iHP on the base unit controllers are iSCSI Host Ports that are used to connect the array
